With the first week of NFL free agency in the books -- and more than 100 unrestricted free agents off the market -- NFL Nation reporters grade the moves each team has made, evaluate the most significant signings -- and losses -- and assess what's next.

Tampa Bay Buccaneers: The Bucs added a significant boost to their passing game with wide receiver DeSean Jackson, but they still have needs at safety, backup quarterback and on the O-line. Read the post here.

Grade: B

Arizona Cardinals: The Cardinals have signed four free agents and re-signed three of their own, but no move was bigger than the signing of a 42-year-old kicker. Read the post here.

Carolina Panthers: General manager Dave Gettleman did a solid job of filling needs at defensive end, defensive back and left tackle in free agency but could have done better at wideout. Read the post here.

Denver Broncos: When the Broncos reeled in guard Ronald Leary, the team got an ascending player headed into his second contract who fills a gaping need. Read the post here.

Los Angeles Chargers: The Chargers got the upgrade at left tackle they coveted in free agency, but they also said goodbye to an integral part of their running back corps. Read the post here.

Philadelphia Eagles: The Eagles needed to upgrade at receiver, and they accomplished that in adding Alshon Jeffery. While the offense got plenty of attention, the defense was ignored. Read the post here.

San Francisco 49ers: The 49ers were the most aggressive team in free agency in terms of sheer player volume, and though they spent money, they didn't do so frivolously. Read the post here.

Grade: C+

Chicago Bears: Quarterback Mike Glennon is a relatively unknown commodity, and the Bears' 2017 free-agent class ultimately will be judged by his success or failure. Read the post here.

New York Jets: Team officials refuse to say they're rebuilding, but that's exactly what's going on -- and that's OK. Read the post here.

Pittsburgh Steelers: The Steelers aren't a team with many glaring needs, but they've mostly waited on the sideline while they still need pass-rushers and cornerback depth. Read the post here.

Grade: C

Houston Texans: One week into free agency, the Texans have lost three starters on defense and have signed only three players -- all re-signings. Read the post here.

Indianapolis Colts: The moves made to this point don't put the Colts back at the top of the AFC South, but it's a process that could take time, which could prove to be an issue when you consider quarterback Andrew Luck is entering his sixth pro season. Read the post here.

Kansas City Chiefs: The Chiefs didn't have much to spend, and with free agent Dontari Poe seeking a huge payday elsewhere, they made sure to fortify their defensive line. Read the post here.

Seattle Seahawks: The Seahawks went into the free-agency period hoping to improve their offensive line, and signing Luke Joeckel is a gamble. Read the post here.
